It is also referred to as a video management server or video management software. It is a component of the security camera system and can also be a software component of a network and a digital video recorder; however, technology has advanced. There is a difference between a video management server and a network video recorder. Despite these network video recorders being able to record and review videos without using a VMS, they have restricted access across other network cameras. For video management servers, they provide more features and capabilities than network cameras. VMS are components of security systems that obtain videos from various sources other than just cameras, record and store those videos, and provide a connection to viewing and accessing live and recorded videos, respectively. The lower the cost of a video management system, the lesser the features available.
Here are some of the features of a VMS;
It has motion detection.
This feature reduces what the camera is supposed to record. Unlike in the past, where security cameras could only do video signal processing using VMS, cameras can now send video when any motion is detected. Motion detection is distributed mainly to prevent cameras from detecting themselves. The video management needs to have in-built motion detection to enable it to carry out this task.
The processing in the VMS is distributed.
Large security camera systems have many data to analyze and store that a single server would be overwhelmed by the workload. The workload can be divided into various devices for each to handle a portion of the workload. However, a video management server provides a single interface connection where clients can access all servers. It brings the sources together and makes it easier for a client to access any source. This feature, however, is not available in less expensive VMS products.
A video management server has audio and alarm input/output features.
It can record audio and, in some cases, act as an intercom through network cameras. It requires an amplifier and speaker. These two are external. You may find a network camera with in-built microphones or perhaps external input/ output audio connections in some other instances. Alarm I/O in VMS can monitor alarm inputs and perform other functions like sending alarm outputs that activate equipment like lighting or sending alert messages to more than one person.
A VMS can also control pan tilt zoom cameras.
These cameras can monitor large areas and provide details of specific points of interest. There are three ways in which this feature can be implemented; a digital translation of a fixed view, an analog motion control, or a combination of both.
Video management systems also have diverse recordings.
A VMS incorporates both analog and digital recording and can accept input from either source.
- It can also connect points of sale such that it is easy to track the sales, mistakes, and potential theft when linked to the output of an electronic cash register.
